What is the primary use of a tri-point screwdriver in iPhone repairs?

The primary use of a tri-point screwdriver in iPhone repairs is to remove the panel covering the battery and screen connections. This specific screwdriver is designed to accommodate the unique screws used by Apple in their devices, which often have a tri-point (or Y-shaped) head. This design enhances security and prevents unauthorized access to internal components. The removal of the panel is crucial during various repair processes, including battery replacements, screen repairs, or other internal component work, as it allows technicians to safely access and disconnect the battery and screen connectors. Properly utilizing the tri-point screwdriver ensures that repairs can be performed without damaging delicate components or voiding warranties.
